dsolve series, number of terms?

Alfred_F — Mon, 31 Aug 2026 08:46:20 Z

I would like to solve a differential equation using a series expansion in the attached file for practice purposes. How can the number of terms in the series solution be adjusted? I couldn't find anything about this in the help text.
BTW:
The differential equation is exceptionally tricky for a symbolic solution ;-) .

Drawing planes and points

erik10 — Sat, 29 Aug 2026 21:56:03 Z

Dear Maple users

I wanted Maple to draw two planes in 3D with some points on each plane. Each plane are given by an equation of the form a*x+b*y+c*z+d=0. I know there are a number of options.

1. implicitplot3d.

2. Isolate z in the equation in order to plot the plane as the graph of a function of two variables using plot3d.

3. Find two vectors orthogonal to the normal vector and create a plot of a parametrized surface using plot3d.

4. Use the command PlanePlot from the Student:-LinearAlgebra package.

The first option delivers an ugly result due to the grid. It also requires quite a lot of computation internally. The second option can be used, but one need to isolate z in the equation (and what if the plane has the equation z = constant). Option three also is OK, but again require some calculations. The fourth option I just found and it is quite interesting. Unfortunately my points did fall beyond the small square representing the plane, and it seems like there is no way to enlarge this square.

I ended up choosing option 2 and put some transparency on each plane. I am just puzzled why it is so laborious to plot those planes and points. GeoGebra could do it right away.

Or maybe I have overlooked something?

KInd regards,

Erik

Solver takes hours to return

I have a very large system of nonlinear equations in Maple 2025, and the solver takes hours. Any Suggestions?

How to deal with this AI prompt error

C_R — Thu, 27 Aug 2026 19:54:59 Z

After starting Maple

I then tried simpler prompts like "Hello", simplify(x),...

For all prompts I get the same error message.
I am not a frequent AI user but this is the first time I see that.
Has anybody else experienced the same?

Can someone send me a prompt that should work?

(Model type was Simple.)

Update:

It seems that this error occurs, when a second instance of Maple 2026.1 is started and AI is consulted in this instance.

Why is D not efffective on (ln@cosh)

C_R — Thu, 27 Aug 2026 17:04:15 Z

To D(ln@cosh) I have to add an argument to make it work (Edit: no output returned):

D(ln@cosh)(x);
                            sinh(x)
                            -------
                            cosh(x)

According to ?D I expected output according to this

Using simplify and implicitplot for ODE solutions

Alfred_F — Thu, 27 Aug 2026 11:43:50 Z

In the attached file, I have solved an ordinary differential equation implicitly. The simplification that is obviously possible using "simplify" is not being performed. Furthermore, "implicitplot" is not working either. I would appreciate some advice.
